11638 (1997 AH) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1997 AH as potentially hazardous because its orbit does not bring it close to Earth.
1997 AH orbits the sun every 1,410 days (3.86 years), coming as close as 2.01 AU and reaching as far as 2.91 AU from the sun. 1997 AH is about 7.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
1997 AH's orbit is 1.03 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
1997 AH's orbit is determined by observations dating back to Dec. 28, 1988. It was last officially observed on Oct. 27, 2022. The IAU Minor Planet Center records 1,882 observations used to determine its orbit.
